ADJUSTABLE SUPPORT FOR BEDSPRINGS.

Application led October 21, 1927. Serial No. 227,704.

yIhis invention relates to adjustable supports for bed springs or other bed bottoms for facilitating mounting of the bed springs on a bedstead.

In bedsteads which include head and foot frames and side rails connecting the head and foot frames at opposite sides, the side rails are not always spaced apart the same distance. In metal bedsteads, the side rails are oi'ten spaced apart a distance somewhat greater than the distance at which the corre sponding parts of a wooden bedstead are spaced, and it is therefore desirable that some means be provided for enabling the bed springs to be mounted on spaced side rails, the spacing of which may vary in different bedsteads.

The principal object oi' the present invention is, therefore, to provide an adjustable supporting means connected to the bed springs for facilitating mounting of the bed spring on various bedsteads in which the distance between the side rails varies with each bedstead.

Other objects are to provide anadjustable supporting means which is adapted tol be locked in operative position; to provide locking means which is operated or rendered efiective by the weight of the bed spring when mounted on the bedstead; to provide an adustable support which will directly transmit the load ot the bed spring to the side rail of the bcdstead; to provide an adjustable support which is readily adjustable to the desired position without the aid of tools or other devices; andin general7 to provide an improved support of the class described.

Further objects and advantages of the invention will be understood by reference to the following speciiication and accompanying drawings in which I have illustrated a selected embodiment of my invention in connec tion with a coiled spring type of bed spring and its manner of use for supporting the bed spring on a metal bedstead and also a wooden bedstead.

In the drawings:

Fig. 1 is a cross section through a portion of a bed spring embodying my improved adjustable supporting means, and through an angle iron side rail Aof a metal bedstead.

2 is a plan of a portion of Fig. 1.

Fig. 3 is a section correspondingto a portion et Fig. 1 but showing my improved support used ter mounting the bed spring on a wooden bedstead in which the side rails are closer together than the angle iron side rails ot the bedstead contemplated in F ig. 1, and

Fig. 4 is a section on the line l--z of Fig. 3.

Referring now to the drawings and more particularly, Fig. 1, I have shown a portion of a bed spring including an angle iron main frame portion 10, which constitutes one side ot a generally rectangular trame which extends around the bed spring. Spring supporting slats, one of which is indicated at 1l and provided with upwardly extending end portions such as shown at 12 are secured to opposite side portions of the main frame by suitable means such asriveting, as indicated at 13. A plurality of coiled compression springs, a portion of one of which is shown at 14 are mounted on the spring supporting slats 11 and tied thereto in any suitable manner and are preferably anchored intermediate 'their top and bottom coils to intermediate coils of adjacent springs or to a stationaryl portion of the main frame as by means of helicals such asV shown at 15. Border coil springs such as 16 are mounted on the horizontal portion 17 of the ends of the sprino' supports, and have their top coils connected to a border wire 18 in any suitable manner. l

It has heretofore been common practice to mount` the bed spring on a bedstead by placing the horizontal flange of the angle iron main frame directly on the top ot the side rail ot the bedstead. However, it has been found that in many bedsteads, particularly metal bedsteads, the side rails are spaced too far apart to permit such mounting. For overcoming this diiiiculty, I provide an adjustable support which in the present instance includes an arm 2O which is slidably mounted in a relatively long but narrow horizontally disposed slot 21 provided in the vertical flange 22 of the main frame and a part 23 which is secured to the outer end of the arm 20. The part 28 preferably consists of an angle iron member including a horizontal flange 24 which is adapted to engage the top of a side rail or as shown in Fig. 1, to engage the horizontal flange 25 of an angle iron side rail 26.

The angle iron part 23 is arranged so that its horizontal flange engages the horizontal Harige of the side rail and also the under side of horizontal Hange- 27 of the traine of the bed spring. It will thus be apparent that the load of the bed spring is transmitted directly through the angle iron part 23 to the side rail of the bedstead. The angle iron part 23 is prevented from turning upwardly about the outer edge of the horizontal flange 27 of the main frame by means of the arm 2O which is limited in its vertical movement adjacent its inner end by means of a bracket member 23 which is secured to the vertical flange 22 and provided with a slot 29 for receiving the inner end of the arm `20. The bracket 28 is preferably U-shaped, as best shown in Fig. 2 and is preferably secured to the vertical flange 22 by means of a pair of ears 30, which extend through suitable slots in the vertical flange and are then bent outwardly to lock the bracket in position. rI`he inner end of the arm 20 is preferably notched as shown at 31 and the relatively narrow lug port-ions 32 and 33 are then bent in opposite directions as shown in Fig. l to prevent passage thereof through the slot 29.

For locking the arm 2O and the part 23 in the desired operative position, I provide the bar 20 with a plurality of notches or recesses 34 and 35 yadjacent opposite edges thereof and the vertical flange 22 of the main frame Withfstops or ears 36 and 37 depending into the slot 21 kfrom the upper edge thereof. l/Vhen the part 23 is in operative position as shown in Fig. l, that is, with its horizontal flange 24 engaging the horizontal flange of the main frame, the stops 36 and 37 enter the notches 34 and 35 respectively to thereby prevent movement of the arm 2O through the slot 2l. It will be noted that when the parts are in the position shown in Fig. l, there will be a tendency for the angle iron part 23 to turn upwardly about the outer edge of the horizontal flange 27 of the main frame, and that such turning is prevented by engagement of the inner end of the arm 20 with the lower edge of the slot 29 in the bracket 23. It will be apparent that when the weight of the bed spring is removed from the part 23 so that the arm 2O may move downwardly in the slot 21, the arm may then be moved through the slot to the desired position of adjustment and the stops 36 and 37 again brought into engagement with the desired recesses. As best shown in Fig. 2, the recesses are arranged in pairs, one being disposed opposite another on opposite edges of the arm.

In Fig. 3 I have shown the relative position of parts when the bed spring is mounted on a bedstead in which the supporting side rails are closer together than are the angle iron side rails contemplated in the illustration of Fig. l. In the said Fig. 3, a wooden bedstead is contemplated and includes aside rail 38 having a supporting block or supporting rail 39 secured to its inner side for receiving and supporting the bed spring. As

shown in Fig. 3, the adjustable part 20 and 23 is moved to its inward limit of adjustment. In this instance, the vertical flange of the adjustable part 23 engages the ears 30 of the bracket 28 and is thereby prevented from further inward movement.

I have thus provided an adjustable support which readily permits mounting of the bed spring of which it forms a part, on bedsteads in which the spacing of the side rail differs. My improved supporting means is simple in construction, will not readily become damaged and inoperative and is capable of being easily and quickly adjusted and effectively locked in the desired position so that there is no danger of the bed spring slipping olf the supporting rail of the bedstead.

The described details of my invention aie merely illustrative of a single embodiment of my invention, wherefore the scope of the same should be determined by reference to the following claims which should be construed as broadly as possible, consistent with the state of the art.
